NEW YORK MULTIPLE ELECTRIC DISPLAY LAM]? Application filed. February 20, 1931. Serial No. 517,205.

This invention relates to new and useful improvements in a multiple electric display lamp. i

The invention has for an object the construction of a multiple electric display lamp which is characterized by a plurality of light discharging means rotative on an axis and capable of adjustments universally.

' Another one of the objects of this invention 10, is the construction of a multiple electric display lamp which is characterized by a plurality of bands positioned with their axis on a straight line, means for supporting said bands so that they are rotative, means for illuminating the interiors of the bands, and light discharging means on said bands.

A still further object of this invention is the provision of a means for discharging light along the axis of'rotation of said hands.

This invention has for a still further object the provision of means for holding the bands in various rotative adjusted positions.

Furthermore the invention also proposes a means for holding the light discharging means in various universal positions.

It is a still further object to provide a means for supporting the display lamp in various manners.

Furthermore the invention also proposes the provision of meansfor rotating the bands as a unit, selectively, or in certain grouping;

And a still further object of this invention is the construction of a multiple electric display lamp which is of simple durable con- 5 struction, dependable in use and efiicient in action, and which can be manufactured and sold at a reasonable cost.

For further comprehension of the inven tion, and of theobjects and advantages thereof, reference will be had to the following de scription and accompanying drawings, and to theappended claims in which the various novel features of the invention are more particularly set forth.

Fig. 6 is a view similar to Fig. 1, but illustrating another embodiment of the invention.

Fig. 7 is a fragmentary side view of the device showing another modified form.

The multiple electric display lamp comprises a tubular casing 10 preferably nickel plated on the inner surface to reflect the light. a A lamp socket 11 closes one end of the casing 10. This lamp socket preferably should be made of porcelain or other similar material as is customary construction. A lens 12 is mounted on the other end of the casing 10. This lens is supported within a metal frame 13 shaped with screw threads so as to be engageable on complementary threads formed upon the end of the casing 10.

A plurality of cutaway portions 10 are formed in the casing 10 and are covered by opaque bands 14 which are rotative in the casing 10 and spaced from each other. In Fig.1 five of these bands have been illustrated, though any number may be used. Preferably, these bands should be metallic. Spacing collars 15 may be fixed upon the casing 10 between the bands 14. These coverings 15 may be made of metal or any other suitable material.1 A means is provided for holding each of the bands 14 selectively against rotation. This means is in the form ofa hollow projection 16 on each of the bands and housing a spring 17 urging a ball 18 into one of a plurality of recesses. 19 formed in the casing 10. The recesses are arranged peripherally on the casing in a line so as to be in the path of motion of the ball 18 as the band is turned. 7 a

Each of the bands 14 areprovided with tubular branches 20. These branches are so constructed that light from within the casing 10 may pass'through each of the branches. Universal joints 21 are interposed in each of the branches so that the outer sec tions may be turned in all directions. More particularly, each of the branches consists of an inner section 22, an outer section 23 and semi-spherical portions on the contacting ends of these sections interengaging each other to form the universal joint. A means is also provided for holding the oint in various universal positions. This means is in the form of a hollow projection24 on one of each of the pairs of sections forming the branches and housing a spring 25 urging aball 26 into one of a plurality of semi-spherical recesses 27 formed in the other of the sections. A lamp 43 is threadedly engaged at one end 44 within the socket 11 and is of long construction so as to extend substantially the full length through the casing 10.

Lenses 28 close the outer ends of the branches 20. Each of the lenses is supported upon a casing member 29 formed in the shape of a tubular thread element capable of engaging upon complementary threads formed on the outer ends of the branch sections 23 colored glasses or other suitable colored transparent material 28 may be placed in front of lenses 28 to produce any desired color effeet. In Fig. 1 support brackets 30 project from the casing members 15 and are provided r -with apertures 31 for receiving screws or the like to support the device. t is best that the casing members 15 be rigidly fixed upon the casing 10 so as not to be rotative and thus form a rigid support when taken together with the brackets 30. In Fig. 5 a modified form of support is illustrated for supporting the device, which is in the form of a band 32 encircling and fixed upon the socket 11 and connected with a support rod '33 having a large foot 34 for resting upon some flat surface. In Fig. 6 a still further modified form of support has been illustrated, in which a band 35 encircles and is attached upon the socket member 11 and has an en larged flange portion 36 for receiving screws 37 to attach the device upon some object.

In Fig. 6 a modified construction of the device has been shown, in which a means is provided for rotating the bands 14 as a unit, selectively, or in certain grouping- This means comprises flange 38 projecting from the casing 10 near one end of the casing. A spring washer 39 is engaged upon the casing and acts against the side of one of the bands '14. The covering members 15 in this device are not fixed upon the casing but are rotative. The contacting edges of the bands 14 and the covering members 15 are formed with serrations 40 which interenga-ge each other so as to bind the parts together as a unit as regards rotation. The casing 10 is formed with an enlarged portion 41 at its rear end which is formed with serrations 42 engageable against the serrations on the side of the bands 14 which is immediately adjacent it.

The spring washer 39 forces all of the bands and covering members against each other so that the serrations interengage. The teeth 42 from the casing serve to hold all of the bands and covering members against rotation.

Now then, when the band at the extreme left is manually turned, the teeth at the left will ride over the teeth 42 in that all of the bands and the covering members 14 can move slightly to the right under flexing of the washer 39. In this manner all of the bands are moved as a unit. If it is desired to adjust the band 14 which is at the extreme left selectively, then the covering member 15 at the right of this particular band is moved towards the right so that its teeth disengage from the teeth of the band and then the particular band at the left may be selectively turned. In a similar manner any of the bands may be selectively turned. Further, any number 015- ly on the casing so as to direct streams 013719 light through the branches in any desired direction. Then the outer sections of the branches may be bent universally so that the light is properly directed. Various coloring screens may be placed within the dilierento branches to obtain the proper color scheme. Light from the lens 12 may shine towards the rear of the store or on the safe, cash register or other objects and this used as a night protection light. nates the necessity of using other bulbs or lights in the store during night.

While we have shown and described the preferred embodiment-of our invention, it is to be understood that we do not limit our-"- selves to the precise construction herein disclosed and the right is reserved to all changes and modificatlonscoming within the scope of the invention as defined in the appended H claims. 1%
